Prepare Frame Control 0.2.0 for public testing

- Without the maintainer's key, Android compatibility reports stay on the
  Mac and the UI says so; the shared database is never contacted.
- Remove personal infrastructure details from scripts and docs: the Drive
  folder and gog wrapper now come from the environment, and the Chromium
  build host is required instead of defaulted.
- Add an MIT license, tester instructions in the README, and bump to 0.2.0.
